(Mercury) Terrestrial planet, position from the Sun 1st, diameter (km) 4,879, mass compared to Earth 0.055, average distance from the Sun (AU) 0.39, no moons, time of 1 rotation 58.7, time for 1 revolution 88 days. Mercury is rocky with craters formed by meteorites.Closest to the Sun and smallest planet in the solar system. Mercury switches back and forth between being extremely hot and extremely cold.It takes 88 Earth days for Mercury to orbit the Sun. Mercury can only be seen justafter the sun has risen and just before the Sun sets. If you were to stand on Mercury, the Sun would appear two and a half times bigger than it appears on Earth. By the time one year has passed on Pluto (after 248 years), 1028 years have happend on Mercury.
(Neptune) Gas Giant, position from the Sun 8th, diameter (km) 142,984,mass compared to Earth 318,average distance from the Sun (AU) 5.2 number of moons 13, time of 1 rotation 9.9 hours, time for one revolution 11.9 years. Neptune is possibly covered by liquid hydrogen and helium. Neptune was predicted before it was actually seen. Neptune is really cold because it dosen't get much Sun light. The strongest winds in the Solar System have
